As a precautionar measure, 7e recommen* installing 9ixe* .E%A air 9iltration units* in our t7o ;2< lobbentrances$ 8hese units can 9ilter an* scrub excess *ust entering into our buil*ings 7ith optional carbon9ilters 9or 9umes$ !imilar units are installe* in the lobbies o9 !tan9or* 'e*ical Center an* some 6aiser .ospitals 7hile maor outsi*e construction proects are ongoing$
